Evolution of young stellar population (YSP; top panel) and SFR (bottom panel), along the U/LIRGs merging sequence and the post-U/LIRG phase. U/LIRGs from Paspaliaris et al. (2021) are shown in orange, while SF Es and Q Es are represented by blue and red squares, respectively. Error bars indicate the range between the 16th and 84th percentiles from the median. A black line connects the median values indicating the general trend.
